Thank you for the opportunity to help you with your question!
If you're in search of a research question for which you can choose either content analysis, I would suggest thinking about a movie or book you've recently read. A movie works well as you can apply different methodologies to understand the movie. For example, let's you you recently watched "American Sniper." You could then apply the methodologies you learned such as historical or characterization to understand the movie.
Please let me know if you need any clarification. I'm always happy to answer your questions.
